MACHINE FOR PRODUCING BLOWN-GLASS ARTICLES.

- Application filed October 27, 1909. serial- No. 524,994.

To all whom it may concern:

Be it known that I, ORIN A. HANFORD, a citizen of the United States of America, and a resident of Rochester, New York, have invented certain new and useful lmpro'v'e ments in Machines. for Producing Blown- Glass Articles, of which the following is a specification.

Generally speaking the machine forming the subject matter of this application com prises a movable blow-pipe frame adapted to receive and support a blow-pipe with a gather of glass thereon, and to be oscillated to swing the blow-pipe for properly distributing the gather and p'resentingit to the mold, a marverer or block adapted to act upon the gather, molds adapted to close" upon gather and open and be cooled after the blowing, and mechanism for con- -;trolling the air pressure in the gather and as the object of the invention is to dispense as much as possible with the employment of attendants, the machine further provides means whereby a. proper sequence is obtained and the desired interaction of its parts occurs automatically upon the starting of the machine by the workman,

when he has inserted therein the blow-pipe with the gather thereon, although I will describe means whereby the automatic action of the machine in blowing and molding may be dispensed with and-such actions be initiated by an operator when desired.

The automatic action of the machine in blowing and "molding, when such automatic action is present, may follow at a prede termined time interval after a preceding action of the machine (to permit elongation) or may automatically occur after a time interval determined by the condition of the glass itself.

To secure the proper and desirable action of. a machine having the general features of my invention as before described,

'I have devised numerous subsiduary features and my invention therefore further consists in the construction, arrangement and combination of the several parts of which it is composed as will be hereinafter more fully described and be claimed after- I. shall have described the best construction known by me by which the objects above set forth may be obtained although it is obvious that the several features of For clearness I shall specifically describe my invention solely with reference to the accompanying drawings, ,without reference 'to modifications thereof, which while embodying its principles of operation employ equivalent structures, as such changes will nisms together with a motor therefor are mounted, the motor being located in the base of the frame. The blow-pipe frame is carried on-a longitudinal shaft in the head of the main frame, being located in front of thelatter and swinging transversely i across it, While the mold mechanism is located in front of the bottom of the main frame, and below the shaft ofthe blowp ne frame. The marverer is carried on one end of the blow-pipe frame and the blow regulating mechanism upon the other.

The various co-ordinating devices are variously located as may be demanded by the necessities of their construction or operation. In the following description that end of the machine at which theblow-pipe frame is located will be called the front and the terms right and left will refer to the machine as shownin the drawings, although it is obvious that the disposition of the parts may be reversed.

Referring to the accompanying drawings in which corresponding parts are designated by corresponding marks of reference:--

Figures 4, 5, 6, 7, 8 and 9 are about twice the scale of Figures 1, 2 and 3.

The main frame, the several parts of which are marked 1, contains, the motor 2, (Figs. 1 to 3) which through its transverse main shaft 3 andcounte'r-shaft. 4,-geared section head end together by the pinions 5, (seeFigs. 5to 7) drives the several parts to be hereinafter mentioned.

The counter-shaft drives (see Fi 7) through amitregear 6 on its left han end, a corresponding ear 7 fast on the lower end of a vertical sha 8, the upper end of which has fast thereonapinion 9, gearing with a gear 10, looseon the lower endof a vertical counter-shaft 11, the said gear 10' also serving, through the idler 12, to drive the gear 13 fast on the bottom of a second vertical counter-shaft 14'. y

The gear 10 maybe made fast (see Figs. 6 and 7) to the shaft 11 by means of a clutch 15, controlled by a yoke lever 16, pivoted at 16 in the main frame, and the shaft llhas fast thereto a worm 17, gearing with a worm wheel 18', sleeved on a longitudinal shaft 21 carried in bearings 21" in the main frame, so that said worm wheel is intermittently driven by the'm'otor through the clutch 15.

The second vertical shaft 14: has fast thereon (see Fig. 6) -a worm 19 gearing with a worm wheel 20 fast on the shaft 21, so that the worm wheel and shaft'is constantly driven by the motor when the latter is running.

The worm wheel. 18 has fixed thereto (see Figs. 5 and 6) in front thereof a cam wheel a disk 23, driven from such shaft by the clutch 24', controlled by the two oppositely disposed yoke levers 25 and 26.

The gear 5 on the counter-shaft 4 also meshes (see Fig. 5) with a gear 27 on a horizontal'transverse worm shaft 27, mounted in the .base of the frame and gearing with a worm wheel 28 on a horizontal longitudinal shaft 29, which serves as the driver for the blow-pipe rotating, and the marvering and the air control mechanisms. The worm shaft 27 further drives a worm wheel 30,

sleeved; on, a horizontal and longitudinal counter-shaft 31, and adapted to be locked thereto by a clutch 32, whereby the shaft may be driven to actuate the mold manipulating mechanism, the clutch being con .trolled'by a oke lever 33.

A longitu inal' horizontal tubular shaft 34 is carried (see Figs. 1, 4 and 5) in a bearing 35 on the top of the main; frame and has keyed to its prei'ecting forward end a two part casting 36, ivided transversely to the axis of the shaft, the parts of the casting receiving between them the central portions of the two rods 37 and 37, which are spaced apart and form part of a blow-pipe frame 38. The rods (Figs-2 and 3) carry at their'one (upper) end an air head casing 39, and at their (lower) other a casing 40,

' 22, while the shaft 21 has sleeved thereon by whichcasing the ends of the rods are connected. The terms upper and lower here usedhave reference to the position of the frame when placed in the molding position by the rotation of the shaft 34.

Two blow pipe rests are carried on the frame, the upper rest being formed by a notch in a cross head 41 carried by the by the split bearings 39 and is provided,

in the prolongation of the line of the axis of the blow-pipe when inserted in the blowpipe rests, with a chuck adapted to receivethe slightly tapering or chamfered upper end 43 of the blow-pipe 43 which is pro- Vided with circumferential series of recesses 43 near such end. The clutch consists of a cylindrical block 44, contained in a hollow cylinder 45 mounted in the casing, the

block beingprovided at its lower end witlt a central bore 44 provided with a packing ring 44" into which the tapering end of the blow-pipe projects, it being held there in against accidental displacement by radial jaws 46, pivoted at 46 in radial slots in the chuck block, and having their inner ends pressed into the recesses of the pipe by springs 46 in the block. The jaws may be manually retracted for the purpose of placing or removing the pipe from the chuck by a turning ring 47 providedwith spiral flanges 47 and held in place? in the casing opposite the cylinder 45 by a cap 48, the flanges 47 bearing upon corresponding cams 49 upon-a collar 49 which bears upon the outer ends of the jaws 46 to shove them rearwardly and thus move their inner ends, which projects forwardly from the pivotal points 46, outwardly.

The chuck block has a peripheral annular groove 50 into which the transverse bores 50 in theiblock open, such bores communieating with the base of the central bore 44 by the aperture 50". A port'51 in the wall of the cylinder 45 and a port 51 in the wall of the air head afi'ords communication between the cavity formed by the annular groove 50,"and the interior of the air head, the communication thus established being controlled by a poppet valve 51, the stem 51 of. which is actuated by a crown cam 52' on a wheel 52, whichwheel is mounted on top of the casing by being journalled on the projecting upper end of a shaft 53, which projects upwardly through the easing in a bearing 53 located centrally thereof, the opposite end of such shaft being mounted in the casing 40 at the other .end of the blow-pipe frame, The wheel 52 driven by a gear 52 fast thereto and meshing with an idlerv54 mounted. on-the top of the air-casing and driven by a pinion preferably flexible. t

In order to permit theaccurate control" 55, fast on the end of the-shaft 56 contained within thehollow rod 37 and actuated by.

mechanism to be hereinafter referred to. The chuck block 44 has its rear end continued through the top of the air head and.

through the chuck cylinder 45' and has fast thereon the gear 57 which is in mesh with the pinion 58 mounted on a stud 58 on top of the air head, and fast with a gear air. to" the blow-pipe at proper times, while the shaft 53 rotates the chuck block and the" blow-pipe that may be contained therein; 7 Air under suitable pressure is led into the casing 39 by an appropriate conduit 59,

of the pressure in the gather after'the'pipe has been introduced into the machine and prior to the blowing. I place upon the side of-the air head a relief valve 60 communieating with the annular groove 50in the chuck body, the stem 60 of the valve being controlled by a tappet lever 60 pivoted at 61 on'a bracket 6l -projecting from the casing, one end of such tappet being pivoted to the stem and the opposite end thereof' being guided in a slotted pin 61 carried in the end of the shaft 53 and being adapted to be struck by a cam plate 52 adjustably 52, to depress the stem andhold the valve open from the'time the blowr'pipe is in-- secured on the outer face of the cam wheel prevents premature swelling of the bulb by the com-pression'of air which would otherwise occur upon the insertion of the blowpipe in the chuck, and be occasioned by the heating of the entrapped air in the gather, while the opening ofthe valveat'the last named period prevents the reduction of air pressure which would occur after theblowing due to the cooling of the entrapped air.

The bracket 61 also carried an end thrust bearing for the chuck block in the form of meshing with a corresponding gear 63 on the front end of a tubular shaft 64 contained
